can't cast entire screen

Hi everyone, so I just got my Chromecast but I'm having issues casting entire screen on my main PC (laptop works fine). What could possibly be blocking this? I've mess with all my routers setting from 2.4Ghz to 5GHz band and it still doesnt work. I've also tried re-downloading flash, disabled UAC, firewall, anti-virus, and anything I could think of that could cause this. Does anyone have any idea what it could be? I've searched a tons but it doesnt seem to be a common problem. Regular casting works fine but it immediate errors when I try desktop mode.

Comparing between my PC and laptop there is a few software difference.

Definitely try a wired connection if you can - that will help rule out general wireless congestion.

So it was a bandwidth/connection issue. I switch to 2.4Ghz and it works!

My HTPC is using the onboard wi-fi card and it seems picky on the 5Ghz upstream with my router. The strange thing is that I never got that "bandwidth connection notification" or orange icon when Chromecast is having network problem; so I never bother to go back and check.

I also check out the Chromecast app and it doesnt even pick up my 5Ghz band so maybe there is some compatibility issue there.

Thanks all for the help!

Glad you got it figured out. The Chromecast PC app is geared to connect to the Chromecast setup AP which is 2.4GHz.
The Chromecast Android app will use on 5GHz but only after Chromecast is set up, when it isn't trying to actively set up a Chromecast.

First I'd run Chromecast as it is and see if you encounter any issues. If not, you could just leave it alone...
But if curiosity keeps you up at night, it's possible there's a compatibility issue with your HTPC's wireless NIC and your router. Try setting your router's 5GHz AP to a lower speed range and see if that helps the connection stability.

Hi how do I cast to PC? I mean where would I connect the ccast to and what app do I need? I'm new to this lol

Chromecast is made to show video on a television. You could hook it up to your PC monitor if it has an HDMI input, or you could use the CR Cast extension (check FAQ for link) to make computer Chrome act like a Chromecast.

Only really makes sense if you have an HTPC though... otherwise it's like using a TV to remote control another TV.
